So I have read the FAQ, but I still cannot get my three monitors to look the same.
Would anyone be able to help?Monitor 1 (Left): Cheap 1080p IPS Acer R241Y
Monitor 2 (Centre): Acer x34P (IPS)
Monitor 3 (Right): Acer x34A (IPS)
Calibration Device: Spyder 5
I have attached 3 images to this post. But basically, I cannot seem to get my monitors to look the same no matter what. If I set the whitepoint target to 6500k and the white level target to 265 cd then I can get extremely close to that on all 3 monitors, but they ALL end up looking different. The x34 on the right seems to be warmer than the centre, and the centre also seems dimmer than the others even though the white level reads the same (265 cd) on both displays.
What am I doing wrong?
Short answer:
-you own an inacurate measurement device
-even if was very accurate the smaller one may need a different spectral correction than other two
-even with a perfect measurement device (and if your eves are a very close match to standard observer) uniformity problems in your screens could lead to percieved overall mismatch in color & brightnessFirst two complains can be at least partially solved with a visual match (by eye). I think that this is covered by documentation (maybe with other words/sequence):
-With the help of your spyder & monitors’ OSD RGB gain control, set three monitors close to your target (white, luminance)
-Change target white & brightness to “native” ( = do not change white in calibration, you will set manually for each monitor)
-Choose the monitor that looks “whiter”
-Use RGB gain & brightness OSD controls in the other monitors until you get a visual match. Here your eye is the measurement device.
-Calibrate & profile (keep whitepoint and luminance as native/as measured = calibration won’t change them)Third complain (if present) cannot be solved with your displays.
This is just for white & white luminance, each monitor can have different contrast (black may look brighter in one monitor than the others) and that may need aditional match.
Anyway, if you use this setup for gaming there are some games that override graphics card LUT calibration when they go fullscreen. This means that even with a visual match in white & white luminance, each monitor could have different gamma (“darker/lighter colors”) or color tint in greys while gaming.
If this happens and DisplayCAL tray app or other tools like ColorSustainer cannot keep calibration loades in GPU while gaming in fullscreen, you won’t be able to solve this issue with your current monitors.I hope your issues could be solved with just a visual match of your three displays.
Ive had this question for years with a Spyder4Pro without a reasonable software solution. My 3 screens show ~0.5 de, yet they all are significantly different especially when comparing with http://www.lagom.nl/lcd-test/black.php
Netflix recommends CalMAN5 & and SpectraCal C6 for calibration. https://partnerhelp.netflixstudios.com/hc/en-us/articles/215669787-Display-Calibration-Best-Practices
As for games going full screen and overriding the LUT, the solution is simple, create a task schedule with 5 minute interval and use dispwin.exe to reload the calibration profile in the background.
